Junipers L3-interface

1) Создаём VLAN:

root# set vlans <vlan-name> vlan-id <vlan-id> (1..4094)>
root@EX4200-1# set vlans v245 vlan-id 245

2) Создаём vlan.245:

root# set interfaces vlan unit <unit# (0..16385)> family inet address <ip address/mask>
root@EX4200-1# set interfaces vlan unit 245 family inet address 192.168.245.1/24


3) Ассоциируем vlan v245 с L3- интерфейсом vlan.245:

root# set vlans <vlan-name> l3-interface vlan.<unit# mentioned above>
root@EX4200-1# set vlans v245 vlan-id 245 l3-interface vlan.245


4) Ассоциируем vlan v245 с физ интерфейсом ge-0/0/14

root@EX4200-1# set vlans v245 vlan-id 245 interface ge-0/0/14
